The Angarsk refinery was commissioned in 1955 and acquired by Rosneft in May 2007. The refinery ranks among the largest Russian oil processing plants and is a major petroleum product supplier in Siberia and the Far East.
The plant’s crude distillation capacity currently amounts to 11.0 mln tonnes (80.5 mln barrels) per year. Angarsk Refinery processes West Siberian crude oil delivered via the Transneft pipeline system. Prior to its acquisition by Rosneft, Angarsk Refinery processed substantial volumes of the Company’s crude oil under tolling arrangements.
The plant’s conversion facilities include catalytic cracking, delayed coking, reforming, gasoline and diesel fuel hydrotreatment, and bitumen production units. Angarsk Refinery benefits from extensive use of secondary processes and currently has a relatively high refining depth of over 75.5%. The plant produces more than 200 types of petroleum products, including gasoline, diesel fuel, jet fuel, as well as bitumen, coke, and oils of various grades. Petroleum products from the refinery are sold in the domestic market and exported to 14 countries worldwide.
The refinery also provides 600–700 thousand tonnes of naphtha annually as a raw material for the thermal decomposition unit of the Angarsk polymer plant, which produces a wide range of petrochemical products, and is owned and operated by Rosneft.
The Angarsk refinery processed 9.71 mln tonnes (71.0 mln barrles) of crude oil in 2010, which is 1.9% more than in 2009. Saleable products totaled 9.04 mln tonnes (including output from the Angarsk Polymer Plant) and refining depth was 75.5%.
Measures were taken in 2010 to reduce irretrievable refining losses and levels of fuel use. Losses were brought down to 0.71% from 0.96% in 2009.
A complex modernization programme for compliance with the Government’s Technical Regulations on fuels went ahead in 2010, and construction work on the new isomerization complex was completed, representing the first step for increasing output of high-quality automotive gasoline. Design documentation was prepared and MTBE and alkylate units were put in place to meet Refinery needs for high-octane additives.
Design work continued on units for the diesel fuel hydrotreatment complex, and design documents for the project obtained government expert approval. Work began on base design of a unit for hydrotreatment of catalytic cracking gasoline using catalytic distillation technology.
Completion of these projects will enable the Angarsk Petrochemical Company to produce high-quality fuel to class-4 and -5 standards.
